On the i.MX8QM, PCIe link can't be re-established again in
dw_pcie_resume_noirq(), if the LTSSM_EN bit is not cleared
properly in dw_pcie_suspend_noirq().
So, add dw_pcie_stop_link() to dw_pcie_suspend_noirq() to fix
this issue and to align the suspend/resume functions since there
is dw_pcie_start_link() in dw_pcie_resume_noirq() already.
Fixes: 4774faf854 ("PCI: dwc: Implement generic suspend/resume functionality")

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
